A similar study was performed by [1]} for a sample of 2 central galaxies in FGs, using longslit spectroscopy obtained with the 8m Gemini North telescope. The authors found different results for the two BCGs: SDSS J073422.21+265133.9 showed a strong metallicity gradient and a slightly positive age gradient, suggesting a relatively recent episode of stellar formation in the centre. NGC 2484, on the other hand, showed an old stellar population (\(\sim 10\)  Gyr) and a flat central metallicity, that was interpreted as the evidence of an inside-out stellar formation, at least in the final episode of stellar formation.
